AGRICULTURAL IMPLEMENT.

Patented May 2, 1916.

Divided and this application filed August 2,

1915; Serial N0. 43,168;

To all whom t may concern:

Be it known that I, WILLIAM C. TROM- rmnn, a citizen of the UnitedStates, residing at Edgemont, in the county of Fall River and State ofSouth Dakota, have invented certain new and useful Improvements inAgricultural Implements, of which the fol lowing is `a specification.

This application is a `division of an application tiled by me February1li, 1915, Serial No. 6,098.

The objectsof the invention are to provide simple and efiicient meanswhereby a planter may be coupled to a lister cultivator and readilyadjusted to run at any desired depth in the bottom of the furrow, and toprovide means foi1 permitting vertical movement of the planter whilepreventing lateral movement thereof.

lVith these objects in view, the invention consists in certain novelfeatures which are illustrated in the accompanying drawings, andwhichwill be hereinafter first fully described and then Vmoreparticularly pointed out in the claims following the description.

In the drawings: Figure l is a side elevation of a portion of acultivator and a planter having my improvements applied thereto; Fig. 2is a rear elevation of the same; Fig. 3 is a detail 4perspective view ofthe draw-bar; and Fig. 4 is a detail perspective view of the device for4controlling the oscillation of the planter.

In the practice of my invention, I plowV the field in the fall or earlyin the spring by means of a lister plow having a sub-soil attachment,the object of the early plowing being to permit moisture to be caught inthe trenches. The plowed held is then permitted to remainidle until theproper time for planting, at which time the soil will have acquired someheat so that the germination of the seeds will be quickly started afterthey are planted. When the soil has acquired sufficient moisture and hasabsorbed suiiicient heat, I drive over the iield in the previouslyformed furrows or trenches a lister cultivator, indicated at 1 in theaccompanying drawings. This lister cultivator may be of any desired typeand is preferably one employing cultivator disks 2 and having rearwardlyextending beams 3. To a cross bar 4 of the cultivator, I attach a hanger5 having an arcuate slot 6 in its lower portion, and to said hanger Isecure the links or side bars 7 which carry a bolt 8 playing in the saidslot 6. The upper ends of these links or side bars are pivotallyattached to the hanger 5 at apointforming the center of the arcuate slot6, and the lower ends of'. said links or side bars are secured to thefront end of the planter, indicated generally at 10. rl`he lower ends ofthe links are provided with a vertical series of openings 9 so that thelinks may besecured at any desired point vertically of the planter andthe depth at which the planter shoe will run in the bottom of the trenchthereby regulated.

A draw bar 12 is attached to the planter,

,either by the same bolt 13 which secures the links 7 thereto or by aseparate bolt inserted through one of the lower openings in the plantershoe, and the front end of said draw bar is pivotally attached to thelower end of a hanger or lever 141 which carries the usual whiiiietreeor other draft device.v This hanger has itsl upper end connected by alink 15 with an adjusting lever 16 mounted upon the cultivator frame,the function of the said lever 16 being to lift the planter andcultivator and hold the planter in any adjusted position.

The rear ends of the side barsor beams 3 of the cultivator carrystandards 17 which are equipped with cultivator shovels 18 at theirlower ends in the usual manner. To

the side bars or frame 19 of the planter I secure short standards orbars 20 which are equipped with eyes 21 at their upper extremities toloosely engage over the standards 17 whereby the said eyes may slidevertically upon the cultivator standards but will have no lateralmovement with respect thereto. The standards or bars 2() may be, andpreferably will be, constructed of adjustably connected sections so asto accommodate the device to different sizes and forms o-f cultivatorsand planters.

It will be readily understood that, if the planter or the covering wheelofthe same should strike a large clod or other obstruction, verticalmovement thereof will be permitted without causing the same to becomedisconnected from the cultivator, and to permit an extensive range ofsuch vertical movement, I provide a series of extension members 22consisting of sleeves slightly less in diameter than the cultivatorstandards and split at their lower ends, as shown at 23, whereby thesaid lower ends may be expanded and forced over the upper ends of thestandards Vand be held rmly thereon by the frictional engagement. Theeye 2l will belarge enough toride easily over the lower 'l end or jointof the extension sleeve, and a second sleeve may be fitted in the sameman- Y ner uponthe first sleeve, if so desired. In-` asmuch as thekeeper bars form a flexible er loose connection. between the cultivatorstandards and the planter frame, the planter will be kept alined withthe trench while` it is used so thatfthe seed will be planted in a trueline.

The ends ofthe draw-bar 'l2 are formed into forks 2l which lare adaptedto embrace the front end of the planter-shoe and the hanger or lever lllrespectively and thereby prevent twisting of the Ydraw-bar or of themembers Yto which it is connected.` The prov'vision ofthis draw-bareffects an application of the draft directly to the planter so as torelieve the strain upon the cultivator and also cause the planter totravel more easily upon the ground. lt also aids in liftving the shoe ofthe planter to secure ample clearance.

An arm 2.4 Aprojects rearwardly from the bar l anda spring :25 1ssuspendedV from the rear end of this arm, a rod 26 cOnnect-.

ing the lower end of the spring with the planter and a thumb screw 27 atthe upper end thereof serving to regulate thetension of the same. "Whenthe lever 16 is released @and swung forward, the 'springV lifts theplanter and it is distendedwhen the planter is lowered to its work."When the lever 16 isswung forward, as just stated, the draw bar 12pushes against the Vlinks 7 kand the V frontend of the planter so thatthe links and the planter moveV slightly upward and backward so .that4the Vfront end of the planter is raised and its clearance increased.Thedescribed movement of the .several parts Valso causes the wheels ofvthen'cultivatorrto move backward, thereby rocking y'the bar 4 andcausing the beam 3 to swing upwardly at its rear end and engage vunderthe eye 2l so as to lift the rear end of the planter. .j

The. mechanismv employed byme isA obviously simple in its constructionand may be produced and Vapplied to any cultivator and planter at a lowcost. By the use of my vimproved agricultural kmachine in the mannerpreviously stated, the seed will germinatel quickly and all weeds whichmay Copies of this patent may be obtained for .presser wheel of theplanter.

have started at the time of planting will be destroyed. The planter maybe positively maintained in alinement with the cultivator so that theseed will be deposited in the soil loosened by the sub-soiler in thebottom of the furrow and covered by the Should the planter strike alarge clod or other obstruction, it may ride readily over the sameinasmuch as the eyes 21 may move easily and freely over the standards 17but will be prevented from dropping by their contact with the uppersurface of the beams 3. lVhen kthe apparatus has reached the end of afurrow, or for any other reason it is desired to raise the mechanismfrom the ground, the lever 16 is manipulated in the usual. manner. ltwill be noted that the rear ends of the beams 3 lie normally out ofcontact with the eyes 21 so that there is a lost motion connectionbetween the cultivator and the planter permitting the cultivator to beraised about three inches before lifting the planter, and, consequently,reducing the in- The adjusting lever may, therefore, be easilymanipulated and the depth of the planting readily regulated withoutapplying a bend- .ing or breaking strain to any of the parts.

Having thus described the invention, what is claimed as new is l. Thecombination of a cultivator, a hanger depending therefrom, a planter, aconnection between the planter and said hanger, a draft device pivot'edupon the cultivator and extending above and below the same, a eraw-barhaving its ends pivoted to the said planter and lower end of said draftdevice respectively, a lever fulcrumed on the planter, and a connectionbetween the lever and the upper end of the draft device.

2. The combination of a cultivator having standards at its rear endcarrying cultiva-tor shovels, a planter coupled to the cultivator,keeper bars secured to the planter frame and engaging over saidcultivator standards to move vertically thereon, and tubular extensionsadapted to frictionally engage over the said cultivator standards.

In testimony whereof I aiix my signature.
